My glide phase happens at the crest of a hill or on the outskirts of a town with the engine on. The Scanguage shows 250-350 mpg. Not as good as with the engine off but it is less to orchestrate to get the car moving again under power. Sometimes I can anticipate a stoplight and fit a glide in between shifts.
60 mpg hwy highest, 50+mpg lifetime
TDi=fast frugal fun
make NOx not Carbon
